  • Action Potential

    The state in which a neuron reaches its Threshold of Excitation and fires, or sends an electrical impulse down the axon.

  • Ion Channels

    Small tunnels along a neuron that to pump ions from one side of the cellular membrane to the other, which creates an electrical charge.

  • Resting Potential

    The state in which a neuron is not firing or sending a neural impulse and when there is a negative electrical charge inside the neuron.

  • Threshold of Excitation

    The level or point at which a neuron fires, or a neural impulse is triggered.
